shift today from iowa and areas like illinois and indiana because the heat ridge is centered over the top of st. louis. a little bit of a break today in areas like montana, but that's about it. everyone else is going to be just as hot, if not hotter, and it's the humidity. dewpoint measures the amount of moisture in the air, and if you are bottom of 70, you are uncomfortable. yesterday it was in the 80s. it was unheard of, off the charts. all this dark green is where it will be humid and uncomfortable today, and that's much of the country. already the heat index is when you wake up from the 80s or 90s. we have heat warnings in the middle of the country. watch it now in the east. once again, near 100 in so many areas. if not 100, you're at least in the 90s. now here's a look at the weather outside your window. well, we have well advertised heat. there's not a lot of rain out there to be found. we have a couple of areas of showers and storms, but consider yourself lucky if you are one of the few to get cooled off by raindrops today. the temperatures in oklahoma city, just incredible all summer long.
